SPECIFICATION forming part of Letters Patent No. 738,634, datedSeptember 8, 1903.

Applioation filed January 23, 1903. Serial No. 140,205. (No model.)

To all whom it may concern:

'Beit known that I, HENRY O. SERGEANT, a citizen of the United States,and a resident of Westfield, in the county of Union and State of NewJersey, have invented a new and useful Improvement in Governors, ofwhich the following is a specification.

My invention relates to an improvement in governors, and has moreparticularly for its object to provide ahigh-speed governor which isparticularly applicable for use in connection with air-eompressorsandpumping-en- 4 provements in the construction, form, and

arrangement of the several parts forinsuring the successful operation ofthe governor. I A practical embodiment of my invention is represented inthe accompanying drawings,

in Which-- Figure 1 represents the governor in side elevation with theparts in their normal position, the vertically-movablecut-off-controlling box being shown in section; and Fig. 2 is a top planview of the governor, a portion of the cover of the box being brokenaway to more clearly illustrate the parts within the box.

1 designates the driving shaft or spindle. A vertically-movable hollowbox or casing surrounds the rotary shaft 1. To the bottom 2 of the boxor casing is connected the upper end of a hollow shaft 3, which in turnsupports the dash-pot rod 4 and cut-off rod 5. The cylindrical wall 6 ofthe hollow box projects upwardly from the bottom 2, forming the bodyportion of the box, and a cover 7 is.

provided for inclosing the box. A drivingsleeve 8 is fixed to the shaft1 within the box by any suitablemeans, such as pins or screws 28, whichsleeve is provided with a pairof outwardly-projected arms 9 and 10,having antifriction-rollers 11 and 12, each of which engages a track 13for connecting'the box tothe shaft, so thatit may be driven thereby, andat the same time permitted a vertically-' sliding movement along theshaft. I provide a weighted toggle-joint connection between the box andthe rotary shaft for controlling the rise and fall of the box accordingto the speed of the shaft, which connection is constructed,

arranged, and operated as follows: The sleeve 8, which is fixed to theshaft 1 within the box,

is provided with a pair of laterally-projected branches 14 15, to thefree ends of which are 20 or the hinge-pintle 21, as the case may be.

These weighted arms are further provided with cut-away portions 26 27for receiving the links 16 17 to permit the lower ends of the said linksto be hinged at the centers of the cylindrical portions of the saidweighted arms. The weighted arms 18 19 are hinged to the bottom 2 of thebox a greater distance from the rotary shaft than the points at whichthe upper ends of the links 16 17 are hinged to the branches 14 15 ofthe driving-sleeve 8.

When the governor is at rest, the hinged connections 22 23 between theweighted arms 18 19 and the links 16 17 are in alinement with the hingedconnections of the weighted arms with the bottom of the box and thehinged connections of the links with the driving-sleeve, thus forming atoggle-joint connection between the driving-sleeeve and the box.Furthermore, the arrangement of the hinged connections of the severalparts is such that the weighted arms exert a constant downward pressureupon the box, even when the governor is at rest, for insuring the fullmovement of the cut-off device in this direction.

In the present form I have shown the branches 14: 15 as being extendedfrom the driving-sleeve 8 at right angles to'the driving-arms 9 and 10thereof, so as to leave ample room for the use of weighted arms 18 and19 of the desired weight to suit different requirements.

By the use of the governor as hereinabove described I am enabled toprovide a device in which the friction incident to the engagement of thebox with weighted rollers is obviated and am, furthermore, enabled toprovide a device which will insure the return of the box to its normalposition when the speed of the shaftvis not sufficient to operate thegovernor.

What I claim is 1. In a governor, a rotary shaft, a vertically-movablehollow box driven thereby and a weighted toggle-joint connection betweenthe box and shaft.

2. In a governor, a rotary shaft, a drivingsleeve fixed thereto, avertically-movable hollow box driven by the shaft and inclosing thesleeve and a weighted toggle-joint connection between the box and thesleeve.

3; In a governor, a rotary shaft having a driving-sleeve fixed thereto,branches extended from the sleeve, a vertically-movable hollow boxdriven by and inclosing the sleeve and weighted toggle joint connectionsbetween the box and the said branches of the sleeve.

4:. In a governor, a rotary shaft, branches supported thereby, avertically-movable hollow box driven by the shaft and weightedtoggle-joint connections between the box and the said branches.

5. In a governor, a rotary shaft, branches supported thereby, avertically-movable hollow box driven by the shaft and weightedtoggle-joint connections between the bottom of the said box and the saidbranches.

6. In a governor, a rotary shaft, branches supported thereby, avertically-movable hollow box driven by the shaft and weighted armshinged to the bottom of the box and links connecting the arms. andbranches.

7. In a governor, a rotary shaft, a drivingsleeve fixed thereto havingbranches extended therefrom, a vertically-movable hollow box driven bysaid sleeve, weighted arms hinged to the bottom of the box and linksconnecting the arms to the said branches of the sleeve.

8. In a governor, a rotary shaft, branches supported thereby, avertically-movable hollow box driven by the shaft, weighted arms hingedto the box, links connecting the arms to the branches, the hingedconnections between the arms and the box being at a greater distancefrom the shaft than the points of connection between the links and thebranches.

9. In a governor, a rotary shaft, branches supported thereby, avertically-movable hollow box driven by the shaft and toggle-jointconnections between the branches and box arranged normally at an angleto the shaft.

.In testimony that I claim the foregoing as my invention I have signedmy name, in presence of two witnesses, this 2d day of January, 1903.

HENRY G. SERGEANT.
